Specification of Letters Patent.

Patented Apr. 11, 1916.

Application filed March 25, 1909. Serial No. 485,853.

T 0 all whom it may concern Be it known that I, JAMEs HAYS ALLIN, a citizen of the United States, residing at East Chattanooga, in the county of Hamilton and State of Tennessee, (and whose post-oliice address is J. Hays ALLIN, East Chattanooga, Tennessee,) have invented certain new and useful Combination-Shafts, of which the following is a specification.

The invention relates to new and useful combination shafts which constitute a part of a vehicle and also a part of a harness;

and in which a pair of guiding shaft-trace elements, movable to and fro endwise, and sharing equally in the guidance, control and draft of the vehicle, are employed. And, for the full protection of such invention, I this day file three separate but companion applications each for combination shafts, and of successive serial numbers beginning with this. I also filed, May 29, 1907, a companion application, covering means for detachably and interchangeably connecting common and shaft traces to hames or other parts of a harness, Serial No. 376,273.

In this invention, the two side shaft members are converted into guiding-shaft-trace elements movable to and fro endwise, and the whiflletree is likewise converted into a guiding-draftuvhiffie-element by hinging the shaft-trace-elements, intermediate their ends, to the respective ends of the whifiletree element of the vehicle, and by movably connecting the rear ends of the guiding-shafttrac elements respectively to the vehicle; and substantially as illustrated in the drawings. Thus these combination shafts are adapted to all styles of vehicles. And they are also adapted to all styles of harness, by being provided, as illustrated, with permanent means for harness attachments in three different localities thereon,preferably at the tips, for direct attachment to the shoulder member of the harness; at the back band locality, for attachment to short tugs, and at the whifiletree connections for attachment to and use with long tug harness, the same as common shafts, when emergency or necessity may require.

The draft and controlling elements of this combination-harness may consist simply in these combination shafts detachably hinged to a hameless steel collar, to common hames and collar, or to a breast harness in combination with the means commonly used in two-horseor pole harness for holding the shoulder member down or back against the shoulders of the draft animal. It should be observed, for instance, that a most excellent combination metallic harness may be prov ded by a hameless steel collar detachably hinged to the tips of a pair of these combination steel shafts; when combined, for holdback purposes, with a light back-and-belly band, or a surcingle, and a choke or polestrap securing the bottom of the collar to the belly-band or surcingle; or when combined, for hold-back purposes, with a crupperstrap attached to the top of the collar and a common hip-strap attached to the crupperstrap, and thence passed down and around the body of the draft-animal and united with a choke or pole strap attached to the bottom of the collar. The single rig thus harnessed may be as easily held back and controlled from the tips of these combination shafts, as the two-horse. or pole rig is so universally held back and controlled from the tip of the'pole by these two methods. In this way it is hoped to entirely dispense with the necessity for the usual expensive, filthy and chafing rear breeching for buggies and other light rigs. Moreover, a most excellent and simple means for using short tug breast and other common harness with these combination shafts, is provided for by the little squaredraft-loop, 12, on the shaft at the back-band locality. The shaft being carried by the usual back-band loop and the short tug being slotted and secured to the said draft loop 12. The belly band may also be secured to said draft loop 12. This, indeed, may prove sufiicient for holding back light rigs, simply by the back and belly bands, or similar means for holding back as above described for the tips of the shafts may be employed. 7

The chief object of the invention is to provide for a substantial, convenient and attractive combination shaft-harness; of few parts, perfect in construction and operation, quick and easy of manipulation, humane in the extreme, sightly in appearance, comparatively inexpensive, and of finished interchangeable parts, void of right and left features, and of easy assemblance. It is also designed to thus create a practical steel harness; other than the bridle, lines and holdback features.

Other objects are to practically dispense with the expensive parts of the harness; to absolutely dispense with the breech andtrace inhumane frictional chafing, and consequent marking of the draft animal, by the use of shaft-trace elements, which stand out from the animal, and which freely and perfectly vibrate to and fro endwise in response to iis holding back breech movements equally as well as to his forward draft movements, and preferably, to use light tubular elements secured together, as far as possible, by interlocking screw-threaded parts as the best method for providing perfect interchangeable commercial parts of quick and easy assemblance and of light weight.

Figure l is a perspective view of a device embodying my invention; Fig. 2 is a rear view of the l-shaped hinge-connector, 2, of Fig. 1; Fig. 3 is a bottom view of connection 3; Fig. 1, top and side views of connection 4-; Fig. 5, a. side-end view of connection 5, with the tubular guiding-draft element and tree shown in section; Fig. 6, a side-end and a top view of connection 6, and Fig. 7, a top view of connection 7 Figs. 8, 9 and 10, are side views illustrating modifications of connection 1, and respectively showing connecting means providing to and fro endwise sliding movement for the shaft-trace element relative to the vehicle; the forward end of the shaft-trace-element being shown broken away; and Fig. 11 illustrates a modified side View of connection 8, and also modified side and top views of connection 6, of Fig. 1, designed to illustrate suitable simple connecting means for wooden shafttrace elements.

In Fig. 1, I have illustrated the forward portion of a vehicle, comprising a pair of tubular combination shafts, and the fore axle hinged together; the remainder of the vehicle not being shown. In this Fig. 1, the guiding draft element, A, is preferably designed to represent a substantially semicircular tube of special shape and design. It is here shown hinged at its ends respectively to the axle, D, by an ordinary vehicle attaching joint, and also to be hinged to the lower end of the upright V-shaped guidinghinge-connector, 2, by a transverse laterally disposed hinge joint, as at connection 4, and in such manner as secures to said connector, 2, to and fro forward and back hinge movement in a vertical plane. This hinge-connector, 2, is preferably of one piece, folded back at the top. The guiding-draft element, A, is also shown to be centrally hinged to the center of the guiding whiflietree, B, by connection 5 and the guiding shaft element, or guiding-shaft-trace element, C, is shown to be of special shape and design, suited to either the sliding or hinge styles of these combination shaft connections. It is here shown hinged at its rear end to the upper end of the said \I-shaped guiding hinge connector, 2, by connection 3; and also to be hinged intermediate its ends to the end of the guiding whiflletree, B, by connection 6. These shaft-trace elements may be of standard lengths, and suited to either the hinge or sliding connections at their rear ends. The arrangement is such that all these ele ments become guiding elements of the vehicle, and the guiding-shaft-trace element also moves to and fro endwise as the traceelement of the harness. The harness attaclr ing means shown in three different places on the shaft-trace element, may amply provide for attaching any and all styles of harness. 1

Connection 3 is shown in Figs. 1 and 3, comprising a connector, a, mounted on the rear end of the shaft-trace element, C, by interlocking screw-threaded arts. The parallel dotted double lines s own'in the joint of this and similar connections in the drawings designate the screw threaded interlocking of the parts. The connector, 04, is also shown provided with an oblong socket, Z), therein, open at the bottom, and closed at the top, for cleanliness of joint and neatness in appearance, and with the upper end of the upright V-shaped hinge connector, 2, hingedly bolted thereto, Within socket Y). The length of the oblong socket, b, is shown suflicient to allow only limited forward and back hinge movement for the shaft-trace element, C, with and relative to the guidinghinge-connector, 2.

Connection 4 is shown in Figs. 1 and 4, comprising a triple-j oint-connector, c, mounted on the end of the guiding-draft-element, A, by interlocking screw-threaded parts; and also bolted thereto against turning thereon; and the bolt-hole, (l, in the said connector, 0, is shown slightly oblong for easy adjustment of the bolt-holes, as illustrated in the top view thereof where the bolt is omitted for this purpose. The bolting or otherwise securing of this joint against turning is of special and vital functional value in rigidly sustaining the said guiding-hinge connector, 2, in its proper upright guiding relations. This triple-joint connector, c, is also shown provided with a lateral transverse socket, e, therein, carrying a bolt, f, hingedly securing the open ends of the upright V-shaped hinge-connector, 2, thereto, and with forward and back hinged relations thereto, and movable substantially in a vertical plane. This upright V-shaped hinge connector, 2, is preferably so constructed to the better secure perfect sidewise guiding functions to the shaft-trace element, as well as being the strongest and cheapest form of guiding hinge construction. It may, however, be made in any desirable form. The third connecting means of this triple-joint-connector, 0, is the vehicle attacher, g, the which may be of any desirable form.

Connection 5 is shown in Figs. 1 and 5,

as comprising a divided draft-sleeVe, h, on the tubular whiffle-tree, B, and'having a pair of duplicate draft tugs, i, thereon, and a divided draft sleeve, j, on the guiding-draft element A, having a pair of companion draft-jaws, 7c is, thereon, with sockets therein engaging the said draft tugs, i, on the Whittle-tree A. and a bolt passed through the draft tugs i, and through the tree, clampingly secures the divided draft-sleeve, h, to the whiffietree, and also hingedly secures the draft-jaws, 7a 70, to the tugs 2'; and a bolt, passed through the bolt holes, Z, in the divided draft-sleeve, j, and through the guiding draft-element A, clampingly secures the sleeve, y', to the guiding-draft element. The

bolt-holes, Z, in the divided draft-sleeve, j, are preferably made oblong, as indicated by dotted lines, for adjusting the sleeve to different angles on the guiding-draft-element. The tubular whiflietree, B, is shown with a tubular sleeve, m therein, designed to be of suitable length to strengthen the center of the tree. The divided draft sleeves h, and j, shown in the drawings, may be divided on one side only, or may be undivided sleeves if preferred.

Connection 6 is shown in Figs. 1 and 6, as comprising a draft-sleeve, a, mounted on the end of the whiflietree' by interlocking screw-threaded parts, and then bolted thereto against turning thereon; the bolt-holes in the sleeve being preferably oblong as shown, for easy adjustment to the bolt-hole in the tree, and sleeve, 02, is shown with an engaging shoulder, 0, on the end thereof, and with a connecting socket therein for hinge-com nection with the shafttrace element; and a divided draft-sleeve, p, on and bolted to the shaft-trace element, and having a pair of duplicate socketed draft-jaws, q, thereon, is shown hingedly engaging the socketed end of the draft-sleeve, n, on the whiffletree by means of a bolt. This bolt, 7", is preferably shown with ahead thereon adapted for attaching a common trace thereto. The said shoulder, 0, by engaging the side of the shaft, limits the to and fro endwise movement of the shaft-trace element. The divided draft sleeve, 7), may be integral, or simply divided between the jaws, as preferred. The square end of the tree may suffice for the shoulder, 0. 'The tubular shaft, C. is shown strengthened at this joint by atube inserted therein.

Connection 7, of Figs. 1 and 7, shows a draft-sleeve, s, detachably and rotatably mounted on the tip of the shaft-trace element, C, by interlocking screw-threaded parts and having a smooth-surfaced draft socket, t, therein, for breast harness attachment, and also having a screwthreaded socket therein, carrying a correspondingly screw-threaded connector, u," said connector, u, being transversely socketed for detachable connection with collar and hames harness. This connection? provides for triplejointed' harness attachment to meet all possible movements of the draft animal.

Connection 8, of Fig. 8, shows the rear end of the shaft trace element, C, inovably mounted within a guiding-sleeve, which is mounted on the rear end of the guidingdraft-element, A. A cap, 1), fitted to the end of the shaft by screw-threaded parts, secures the shaft within the said guidingsleeve. I

Connection 9, of Fig. 9, shows a'guiding bolt secured to the rear end of the shaft trace element, C, and a guiding sleeve mounted on the said guiding bolt, and hinged to the axle-clipronnector, 9 shown in Figs. 1, 9 and 10. 7

Connection 10, of Fig. 10, shows a'guiding bolt having its head end movably secured within-the rear end of the shaft-trace element, C, by a cap-sleeve, W, closely fitting the bolt and mounted on the end of the shaft by interlocking screw-threaded parts, and the small end of the guiding bolt to be hinged to the aXle-clip-connector, 9 shown in Figs. 1, 9 and 10. Thehinge end of the guiding-bolt is slipped through the capsleeve before attaching the cap-sleeve to the shaft. The endwise movement of the shaft-' trace-element is shown to be limited in each of Figs. 1, 8, 9 and 10. Such limitationsserve to sustain these combination shafts in their proper upright shape and relations of parts at all times. 9 of Figs. 1., 9 and 10, is shown in Fig. 1, to be provided with a pair of jaws, w, for hinging theconnecting means of Figs. 9 and 10 between said jaws, and for hinging the lower ends of the V-shaped guidinghinge connector, 2, of Figs. 1 and 11, to'the outsides of saidjaws, when it isdesirable to so hinge said hinge-connector, 2, directly to the axle in place of to the guiding-draft-element of the'vehicle. The said V-shaped guiding hinge connector, 2, is identical in Figs. 1 and 11, but is shown broken away in Fig. 11. In carrying the invention into e'lfect, the arrangement is such that different modes may be employed for'movably connecting the rear end of the shaft-trace element to the vehicle. For instance: where it is desirable to carry the rear end of the shaft-trace-element high above that part of the vehicle to which it is movably attached, an intervening upright guiding hinge connector may be employed for hinging the rear end ofthe shaft-trace-element to the axle or to the guiding-draft element of the vehicle, and substantially as illustrated in Fig. 1, by'connector 2, in combination with connection 4, or in combination with the axle-clip connector, 9 and where it is desirable to carry the rear end'of the shaft-trace element low, relative to the parts of the vehicle to which The said aXle-clip-connector,

it is movably attached, a sliding sleeve connecting means may be employed, such as illustrated in Figs. 8, 9 and 10. Generally speaking, the upright, intervening hinge connector means, such as 2, is preferable for buggies and other light rigs, and the sliding sleeve connecting means for heavier draft vehicles.

It will be observed that the same shafttrace element is usable on either the right or the left side of the vehicle by simply adjusting the connections; for a shaft element void of vertical bend may be usable either side up or down or right or left, and that it may be of one piece, and desirably tapered, or it may be divided as illustrated at 13, in which case a smaller tube may form the forward part of the shaft, and thus give taper to the tubular shaft, or the shaft may be divided at connection 6, and all the connections may be mounted on the rear portion. The latter division may prove to be the preferred arrangement. It will be observed that in this latter case, the shaft-trace element could beinterchangeable with the shaft-trace element of the said companion application next fol lowing this. These shaft-trace elements may be of finished, interchangeable commercial design, such as any teamster may put to gether. Indeed, the same may be true of all parts of these combination shafts.
